Defects in this process can lead to cell death or diseases like cancer. A new study has shown how chromosomes change shape during cell division. Certain protein complexes help fold DNA into ...

The planned changes include reinstating a version of chromosome testing that was discontinued in the 1990s, requiring athletes who compete in the female category to submit to a cheek swab or dry blood ...

The ‘bunch of dots’ of DNA they saw in the microscope, separated from the chromosomes, but still within the cell nucleus, were often in pairs (now we know because they were replicating). Interest ...

Scientists at EMBL have captured how human chromosomes fold into their signature rod shape during cell division, using a groundbreaking method called LoopTrace. By observing overlapping DNA loops ...

Tumor development is often associated with errors in segregating chromosomes that contain the genomic DNA, which can end up outside of the nucleus. The study shows that missegregated chromosomes ...

To uncover what drives sexual behavior in animals, researchers studied the brain activity of male mice throughout the series of actions involved in sex leading up to ejaculation. Their results ...
